Etymology: Aphids take their name from a mistake. The insects were long called "aphides," a term that came from a misreading in Pliny's Latin, and the English "aphid" was formed from that plural. "Aphidicide" then joins that name to the suffix "-cide," which comes from Latin "caedere," meaning "to cut down" or "to kill." The same suffix appears in "insecticide" and "herbicide," so the word follows a familiar pattern. The second element has a more compact history than the first. Latin "-cida" and its relatives passed into Middle French as "-cide," and English borrowed that form, giving us a family of words built on the notion of killing a specific target. Attaching it to "aphid" produced a term precise enough for growers to name a product that kills one pest group, rather than insects in general.
